like the brightness gets turned down? or it is just harder to see? amoled screens do do better in brighter environments compared to other led screens, but they will still be harder to see in brighter surroundings.
Turn adaptive brightness on
i never use it. i want my screen to be as bright as possible whenever i use it. on the note 10+ this does not hinder battery consumption too much for me.

I can actually watch it dim to the point I can't see the screen. It is so frustrating

How would turning it on keep the screen from getting dark in the sun?
has it always done this? or just recently? try putting it in safe mode and see if it still happens. this will determine if a 3rd party app is the root cause or not.
Adaptive means it should set the brightness depending on the sunlight

Yes it has. My galaxy S8 did too. The phone will get hot too. I just assumed it was the sun
well it could either a software issue which putting it in safe mode might help determine if is or not. also doing a factory reset might determine that as well.
or
it could be a hardware issue which you would then need to get it looked at and either fixed or replaced.
Don't these devices use some sort of brightness boosting when in bright light (at least in automatic brightness mode, where the maximum brightness is double what it can do manually)?
If so that will generate a lot of heat, and prolonged running like that would damage the display. So to protect the device and the display I'd expect it to turn the brightness down after some interval of running like that, which fits with the observation that the brightness decreases after a while. If the S8 did it as well that tends to support the theory that this is what's happening, as does the comment that the phone gets hot.
Such boosted brightness is intended to allow you to read a message or take a photo in bright light. It's not intended for continuous use. Since the brightness boost doesn't happen in manual brightness mode if @ocnbrze isn't using automatic brightness control I'd expect it to maintain a constant but lower brightness for him.

Is there an app that can possibly cool down my cpu? Would that help the screen lighting?
The only thing that can cool the cpu (or rather the SoC, since the gpu is a major heat source as well as the cpu) is running slower. Perhaps turning the power saver on (I assume Samsungs have something like this, since most others do), though that may also limit the screen brightness (but see below on that.
In fact the system will throttle the SoC down if it gets too hot. If the phone were rooted it's possible to produce mods which allow you to change the thermal thresholds so that it throttles sooner. Of course this also slows the system, so if you go in for heavy gaming sessions you wouldn't want this. But in the best case rooting and making such mods requires some learning and not caring about voiding your warranty - if you have a Snapdragon-based S10 rather than a Exynos-based one it's unlikely that you can root it in the first place (but in compensation the Snapdragon ones perform better, and generate less heat for the same performance). Without root you cannot change this. You will find apps in the Play Store that claim to make your phone run cooler, but this is bullshit (task killer apps make a lot of bullshit claims to con mugs into installing them).
In any event the display will still produce a lot of heat at boosted brightness, so if this is what's behind it the best you could hope for would be to extend the time before it happens. You might actually do better by turning the brightness down a bit: running longer, perhaps indefinitely, at a lower brightness rather than a shorter time at maximum brightness may work better for you. In any case you don't want to run the display for extended periods at boosted brightness: OLEDs degrade with use, and the brighter you run them the faster this happens. When I said that prolonged running like that would damage the display I wasn't just talking about heat.
Remember that I don't know for sure that this is what's causing this. It's merely a hypothesis that's consistent with what I know about these phones (I don't own one) plus what you describe. But genuinely, if I owned one and had a hack that would let it run at its boosted 800 nit brightness continuously I would be very wary of using it, since running like that for hours on end would be the quickest way to produce "burn in" on the screen.
